Application filed @ctober 11, 1916. Serial No. 124,941.

T0 all whom t may concern:

Be. it known that l, HARLEY S. Bussy, a citizen of the United States of America, and resident of Vlashington, l.Washington county, Iowa, have invented a certain new and useful Improvement in Heaters, ot which the following is a specification.

My invention relates to an improvement in heaters, and particularly to that type ot heater which is. designed for use in heating small out-buildings or may be submerged in the water of the ordinary stock watering tank to not only pre-vent the same from freezing but to keep the water at a constant temperature during the severest weather.

An object ot my invention is to provide a heater which is very eiiicient in operation and one whose construction is simple and dur ble and in .vhich kerosene may be used as fuel thus avoiding the labor and danger ot lire incident to the use o wood or coal, as fuel as in other terms of burners.

These and other objects my invention will be more readily understood by having reference to the accompanving drawing in which l have illustrated one embodiment of my invention.

Figure 1 is a side elevation partly in section of a heater embodying the features ot my invention;

Fig. 2 is a sectional view taken on the line 2 2 of 1Fig. 1 looking in the direction of the arrows; and

Fig. 3 is a sectional View taken on the line 3 3 of Fig. 1 looking in the direction olf the arrows.

In the drawings l have illustrated a heater comprising the cylindrical body portion 4v which may be made of plate steel and which is provided with a heavy cast metal base 5. secured thereto and made a part thereof by having these two parts molded or fused together in any desirable manner whereby the connection or joint is rendered water tight. This base 5 is of suicient weight to cause the heater to sink to the bottom of' a stock watering tank, and is provided with suitable lugs or feet 6 for supporting the heater and which operate to hold the same a slight distance from the bottom oi"- the watering tank when the heater is employed in such connection whereby free circulation of water is permitted about the heater. A. suitable cover 7 is iitted on the top of the cylindrical body 4, which top is provided with a sliding lid 8. Extending upwardly from the cover 7 is a suitable smoke Hue 9, which is provided at its upper end with a draft cap 10, of any suitable construction, which prevents any possibility oil back draft and also prevents the heat troni escaping through the smoke tlue.

As clearly shown in Fig. l, the base 5 extends to one side of the cylindrical body -l and supports the intake drat't pipe 1l. This draft pipe is provided with a suitable hood 1Q, which hood is provided with a downwardly extending flange 13 which fits over the drat't pipe and is provided with inwardly extending lugs 14, which rest on top of the draft pipe and support the cap a short dist-ance above the upper end ot the pipe. By this construction a suitable supply or.' air may be admitted to the draft pipe but the same is protected from rain or snow.

Passing through the center ot' the dralt pipe 11 is a suitable feed pipe 15 which pipe carries at its upper end a suitable tank 16. A sight dropping feed valve 17 is provided in the pipe 15 by means of which the rapidity o1- iiow of oil from the tank through the Jfeed pipe can be regulated.

At its lower end the feed pipe is secured by a suitable elbow 1S to the laterally extending pipe 19, which in turn is connected by the elbow 2O to the upwardly extending teed tube E21 which extends through the center of the burner plate 22. This burner plate is mounted on a suitabe tlange formed in the base 5 and consists of a circular plate of refractory material provided with a downwardly extending` cone-shaped central portion Q3 through which the feed tube 21 extends. This conicalshaped portion of the burner forms a suit-able recess for the reception of a wick 241 of asbestos or other suitable absorbent material. The burner plate 22 is provided with two square openings 25, located on opposite sides of the central conical portion, and mounted on top of this burner is a hollow arc-shaped cap 26 forming a combustion chamber, which cap is provided with two openings which engage with the square openings in the burner plate and with a central opening 27 immediately above the central portion ot' the burner plate.

It is thought that the operation of the burner will be readily apparent. The Valve 17 is first opened so as to permit the oil to pass from the tank 16, through the feed pipe 15, and thence to the burner plate 22, where it saturates the wick 24. A lighted match is then dropped through the opening covered by the lid 8 onto the wick and the cap 26 is then placed in position. The flame can then be regulated by adjusting the valve 17 so as to vary the flow of oil. The .air to support the combustion is drawn through the intake pipe 11, thence through the base and then passes through the two square openings in the burner, through the cap 26, and is thus directed to the flame at the center of the burner. From this construction it will be seen that a very eliicient air supply is obtained as the only exit for the air from the base is through the square openings in the burner plate and through the cap 26 by which means the air is carried directly to the top of the flame. It will be noticed that the upper end of the feed tube 21 is reduced in cross-section. With this construction, the tip of this tube becomes heated sufficiently in operation to vaporize the fuel as it is ejected from the feed tube thereby insuring more complete combustion.

A further advantage of my construction is that the feed pipe for the oil passes through the air intake pipe. Thus the cool air passing, through this pipe, tends to maintain the oil feed cool and thus prevents the oil from vaporizing until it strikes the tip of the feed,tube 21. Furthermore by reason of the ldome in the center of the cap obtain a more even and steady flame and avoid any flickering. rI his is due to the fact that the air passing upward through the square openings 25 in the burner is directed toward the center of the cap and swirls about in the dome, thus breaking the direct ldraft over the top of the flame and preventing any flickering of the iame which would be caused by such a draft.

It will thus be seen that 1 have devised a very efficient form of heater and one in which the flame can be very easily regulated and also one in which efficient combustion is insured. Also the construction is such that very little heat escapes through the smoke pipe 9, thus more efficient heating effects are obtained.

Vhile I have illustrated and described one particular embodiment of my invention, it will be understood that l do not wish to be limited to the exact construction shown and described, but that various changes and modiiications may be made without departing from the spirit and scope of my invention.

What l claim as my invention is:

1n a heater, a base, a fuel oil burner mounted in said base, said burner consisting of a plate having laterally disposed air openings, a fuel-pipe passing through the central portion of said plate, and having a reduced tip so that the walls are suficiently thin so as to become heated to a degree sufficient to vaporize the fuel emerging therefrom, an arch-shaped air pipe mounted on said plate having terminal openings engaging with said laterally disposed openings and having a central circular opening adjacent the upper end of said fuel pipe,

lsaid air i e beino' also rovided with a cylindrical dome-shaped portion immediately above said fuel-pipe.
